Answer:
The value of the second expression is 14, so the expressions are equivalent.
Step-by-step explanation:
x=5
6+2(5)-2=
6+10-2=
16-2=
14
The other expression also came out to be 14, so they are equivalent.
Answer:90
Step-by-step explanation:
the angle is perpendicular
Use the power rule
d(x^n)/dx = n·x^(n-1)
to form the derivative.
f'(x) = 4·2x -4
f'(x) = 8x - 4
Now, substitute "a" for "x" to find f'(a):
f'(a) = 8a - 4
